Predicted Grasshoppers Development Storymap

  • Cite

The Predicted Grasshopper Development storymap provides weekly predicted stages of development of the migratory grasshopper (Melanoplus sanguinipes) across Western Canada. The migratory grasshopper is one of the most destructive insect pests in western Canada. Outbreaks can lead to costly losses for grain growers. This species attacks both field and garden crops, especially cereals, tomato, celery, onion and carrot.

This dataset provides an estimation of developmental stage of the migratory grasshopper for farmed locations across Western Canada in order to equip producers with information on what may be occurring in their area. Early in the growing season, this information can be used to properly time scouting activities in the field. In fall, information regarding oviposition can be used as an estimate of risk in the next growing season.
